• The law of abstinence forbids the eating of flesh meat and of broth made of meat, but does not exclude the use of eggs, milk and the products of milk (namely cheese and butter), and any seasonings of food, even those made from the fat of animals. (Canon 1250.)
• The law of fasting ordains that only one full meal a day be taken, but does not forbid a small amount of food in the morning and in the evening. As regards the kind of food, and the amount, that may be taken, the approved customs of one’s locality are to be observed. One may partake of both fish and flesh meat at the same meal. The full meal may be taken in the evening and the collation at noon. (Canon 1251.)
• Abstinence only is enjoined on the Fridays throughout the year. Fast and abstinence are prescribed on the following days: Ash Wednesday, the Fridays and Saturdays in Lent, Ember days, the Vigils of Pentecost, of the Assumption, of All Saints Day, and of Christmas Day. Fast only is ordained for all the other days of Lent. On Sundays and holidays of obligation, except on a holiday in Lent, there is neither fast nor abstinence, and if a vigil that is a fast day falls on a Sunday the fast is not to be anticipated on Saturday but is dropped altogether that year. The Lenten fast and abstinence cease at twelve o clock noon on Holy Saturday. (Canon 1252.)
• The foregoing Canons make no change in particular indults; they do not affect the obligations imposed by vow, either of individual persons or communities, nor alter the constitutions and rules of religious organizations and approved institutes of men or women living in community, even those without vows. (Canon 1253.)
• The law of abstinence binds all who have completed their seventh year of age.
  The law of fasting binds all who have completed their twenty-first year until the beginning of their sixtieth year. (Canon 1254.)
